Letters Patent No.'99,534, dated February 8,1870

The' Schedulerefen'ed to in these Lettera Patent and making part ci the same.

To dll to whom 'it may concern Y Be it knownV that I, CHARLES H. CHAPMAN, of

Shirley, county of Middlesex, State of Massachusetts,

lhave invented certain new and useful Improvements in Steps and Bolsters forCotton-Spindles; andI do hereby declare that the4 following 'is a full and co1'- rect ydescription thereof, reference, being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists- First, in so arranging the step and bolster-bearings that they are' perfectly adjustable, one part with another, and also in relation to the frame, so that the bearings of the spindle may be close-iitting, and that the spindle may be adjusted to the exact centre of the ring. p 1

Second, in combining, with the above device, ari improved oiler.

To enable others skilled in the art to make and use my invention. I will proceed to describe its construction and use.

Drawings.

Figure 1 is a perspective view, representing a part of' a frame containing asingle spindleand its adj uncts.

Figure 2 is a vertical section` through the same.

Figure 3 is an elevation of the-bolster, showing a part of the spindle.

Figure 4 is a plan oi' same.

A .B C represent-the frame, to which/the other parts are attached.

L is a spindle, andI P, a ring. Y

D, iigs. 1 and 2, represent a base, fastened to the frame-work A, to which the step-hearings are attached.

D' is a base, fastened tothe frame B, to which the bolster-hearings are attached.

As the bolster and step-bearings are essentially alike, I will only describe in detail theIbolster-bearings.

K is a box, formed as-shown in igs. 3 and-4, and is provided with an oil-recess, M; This recess connects,

by a small passage, wit-h the bearing-face of the box, so that the oil may he conducted to the spindle.

The passage M is provided with wicking, which serves to conduct the oil to the bearing..

The box K is provided withslots, through which the screws S S pass.

H forms a counter-box for K, and is made as .shown in iigs. and 4, and is provided with slots, as shown, through which thel screws S S pass. When the screws S and S are screwed hard down, they exert suiicient pressure npon both H and K, to hohl them securely in any desired position.

From the above, it will be seen, that by my invention, a perfect hearing may be had at all times, andthat by a simple adjustment of the bolster-boxes H and K, and the step-boxes E and F, the spindle 'may be brought to a perpendicular position, and to that exact cent-re of the ring which causes an' even draught on. the yarn. The bearings being short, and always in perfect adjustment, it makes a great saving of power, and gives the number of twists desired in the yarn, especially when there are loose bands on the traine.

As both steps and holsters are provided 'with perpetual oilers, the spindle will move so easy, that the Ioosest band will operate it. A great saving of oil and labor is also made.

Claims.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. The combination of the boxes K and H with the base D and spindle L, operating as either bolster or step, substantially as described, and for the purpose '2. The combination ofthe oiler M with the box K, operating substantiallyas described, and for the purpose set forth.
